Ruth Mudd-O'Flaherty has been a lone wolf at her new middle school ever since her best friend, Charlotte, ditched her for "cooler" friends. Who needs friends when you have fantasy novels? Roaming the stacks of her town's library is enough for Ruth. Until she finds a riddle in an old book, one that Ruth can't solve alone. With a tantalizing set of clues before her, Ruth must admit she needs help, but Ruth must decide: Is embarking on this quest worth opening herself up again?
